MlTERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 710,479, dated October 7, 1902.

Application filed April 28, 1902. Serial No. 104,940. (No model.)

To all whom, it may concern:

Be it known that 1, JAMES LOCKE, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Mitering-Wlachines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in mitering-machines, the features of which will be fully hereinafter described and claimed.

The object of my invention is the construction of a device adapted to sawing at any desirable angle by either a right or left handed person and to adapt the same to sawing edgewise as well as fiatwise. The objects are accomplished by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a plan of the machine. Fig. 2 is a front elevation with onlya part of the top of the frame illustrated. Fig. 3 is aside elevation. Fig. 4 is a side view of the clamp. Fig. 5 is a horizontal section on line :0, Fig. 8. Fig. 6 is a vertical sectional view of the adjustable arm and the'guide.

Like letters and numerals designate like parts throughout the several views.

The frame comprises two parts, the triangular-formed base A and the vertical part A. The former is mounted on feet, giving a slight elevation, as shown at Fig. 3. The base is provided with the ears 9 9, which are threadd to engage the screws binding the two parts. Near the center of the base is an ob- .long quadrangular orifice 19, the ends terminating in circular orifices opening into said quadrangular orifice. (Shown at Fig. 5 and is not shown in the plan view at Fig. 1.) This central orifice is for the purpose of passing one end of the clamp through the base, and the position of clamp E is shown in this figure. The clamp comprises the body E, the two legs formed at a right angle, the traversing arm 14, held on one leg, the screw in end of said arm, face 13, with the screw held in said face. To pass the end of the clamp through the base, turn it slightly until it will pass through the orifice, bringing the head of the screw 20 into the circular orifice, and thereby is given support to the lower end of the clamp. The position of the clamp in its relation to the base is shown at Fig. 5. The vertical part A of the frame comprises the projection 21 as a support for the pivotal screw 8, the bearing-lugs 6 7, and identical lugs on the opposite surface, (see 19, Fig. 1, that opposite 7 not shown,) the notch 10, orifice 11, and the quadrangular orifice 22. The notch and orifice beneath are to receive the clamp E when in the position as shown in Fig. 1. The orifice 22 receives the clamp when sawing the face of boards, and the notch and orifice beneath are used when sawing through the boardedgewise. The lug 16 at the top of the frame supports the screw 1'7, to which is attached the crank 18. The screw is pointed to enter the orifices of the indicatorplate. The indicator-plate B is pivoted to the near end of frame on the screw 8. It is of the form shown in Fig. 1, having a circular edge in the rear and two cars 5 5 on the front edge, and these ears form the support for the adjustable arm 0. The series of orifices 1, 2 2, 3 3, and 4 4 are points of adjustment. When the point of the screw is entered in orifice 1', the board would be sawed at a right angle to its edge, at 2 would have the angle of a hexagon, at 3 the angle of an octagon, and at 4 the angle of forty-five degrees. The arm 0 is held to the indicatorplate by the screws '6 (see Fig. 2) and can be adjusted vertically and laterally to suit the position desirable for the saw. It is dovetailed into the ears of the indicator-plate. On the lower end of this arm in a lug is socured the screw 12 for the purpose of holding the saw-guide.

The saw-guide comprises two like parts united at their tops by the series of screws 8, one at the top, and two lower are in line, the guide parts having vertical portions, through the upper ends ofwhich said screws 8 pass, and a lower horizontal portion having registering horizontal slots. The slot in the outer is wider than the inner, and on the edges of the inner the screw-head bears. To saw with the right hand, the saw-guide is attached as shown in Fig. 1, the indicator-plate being turned to the left to secure the proper angle, and for a left-handed person the arm 0, with its sawguide, is attached to the right ear and the indicator-plate turned to the right. To saw the face of the board at an angle, the face end of the clamp is placed beneath the base, as shown at Fig. 5, and the same is bound against said base by the screw of the clamp. To cut a board edgewise, detach the baseplate and let the side lugs rest on the edge of said board. Then move the indicator-plate to suit. The clamp is held in the orifices of the frame, and thereby the board is bound against the side thereof.

Boards may be sawed on both sides of the vertical part of the frame, it only being necessary to change the position of the saw-guide from one side to the other of indicator-plate and change the position of the clamp in the vertical orifices or the orifice in the base, into which it will enter in both directions.

Having described my invention, what I claim is 1. In a mitering-machine the combination of the vertical frame provided with hearinglugs, orifices for the reception of the clamp and the pivot-lug; the pivotal screw held in said frame, the indicator-plate provided with ears and the screw to hold said plate in position, substantially as described.

2. In a mitering-machine the combination of the frame comprising the base and vertical parts, said base having an oblong quadrilateral slot and the communicating orifice to engage the head of the screw, the vertical parthaving a perpendicular slot the clamp provided with said screw and adapted to enter said slots of the frame, substantially as described.

3. In a mitering-machine the combination with a base having a vertical middle portion, or flange of a saw-guide having a supportingpivot at the top of one end of said flange, and swinging around said end of said flange,

and an indicator-plate playing over the top of said flange, and indicating the angle of the saw-guide to one or the other side face of said flange, and means for securing the angular adjustment of said indicator-plate, substantially as described.

4. In a mitering-machine the combination of the frame provided with circular orifices having side openings to a lengthened slot, the clamp comprising the body, the engaging face with holding-screw secured therein, and the binding-screw, substantially as described.

5. In a mitering-machine the combination of the pivotal indicator-plate provided with ears, the arm rigidly secured to one or the other of said ears, the saw-guide of two similar parts the inner one secured by screw to the lug of said arm, the same being adjustable vertically by said arm and adjustable from a horizontal plane by the screw holding said saw-guide, substantially as described.

6. In a right and left hand mitering-machine the combination of the frame comprising parts A, A, the former having a central longitudinal slot, the latter having a vertical slot in line with said longitudinal slot, the latter having a perpendicular slot and a notch and slot in vertical line, these being provisions adapted to the use of a clamp, the indicator-plate with a series of circular orifices, the screw to engage these orifices for adjustment and provided with ears, the adjusting-arm held to one of said ears, the sawguide held pivotally on said arm, and the clamp to bind the material, substantially as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of, two witnesses.

JAMES LOOKE.
